HARRY C. GAMMETER, 0F CLEVELAND, OHIO, ASSIGNOR TO THE AMERICAN MULTI-GRAPH COMPANY, OF CLEVELAND, OHIO, A CORPORATION OF OHIO.

COLUMN-RULE.

Application filed July 21, 1913.

T 0 all whom it may concern:

Be it known that I, HARRY C. GAMMETER, a citizen of the United States,residing at Cleveland, in the county of Cuyahoga and State of Ohio, haveinvented a certain new and useful Improvement in Column-Rules, of whichthe following is a full, clear, and exact description, reference beinghad to the accompanying drawings.

My invention is particularly applicable to printing machines of the typeknown commercially as the Multigraph comprising a rotary printingcylinder having a series of under-cut channels in its perimeterextending parallel with its axis to receive complementary shaped flangedtype which said cylinder presents in opposition to the other member ofthe printing couple. As ordinarily constructed, the only means withwhich such a machine is provided for printing lines at right angles tothe lines of letter type consists of type fitting to the channels andhaving dash faces. Consequently, a series of such separate type must beused to print a line of greater extent than the dash carried by the faceof a single type, and, unless said line type are accurately set andprovided with means to hold them in alinement, they print a broken lineinstead of the continuous line desired.

Therefore, it is the object of my invention to provide such a machinewith means to present a continuous printing face to print lines at rightangles to the lines of words, and, as hereinafter described, such meansincludes a rule strip curved to fit circumferentially upon said printingcylinder and preferably having means fitting in said un dercut channelsthereof adapted to retain it in set position.

My invention comprises the various novel features of construction andarrangement hereinafter more definitely specified.

In the drawings, Figure 1 is a perspective view of my column ruleshowing also a clip engaging its flange; Fig. 2 is a plan or developmentof a rotary railed printing member having type and my column rule1nounted thereon; Fig. 3 is a cross section of a portion of such railedmember showing my rule in side elevation; Fig. 4: is an enlarged crosssection of the rule with a type on one side of it and a holding clip onthe, other side.

As shown in the drawings, 10 indicates the Specification of LettersPatent.

Serial No. 780,159.

body of a suitably curved member carrying parallel rails 11 havinggrooves 12 in their opposite sides, leaving overhanging edges or ledges13.

15 indicates type having grooves 16 in their opposite sides, whereby thetype may be mounted in lines between the rails, the ledges of the railsentering the side grooves of the type.

The construction just described is the usual one in the Gammeter lllultigraph.

The typeholding member may be a complete rotary drum or a segment, asdesired.

My column rule consists of a curved strip adapted to seat on the face ofthe rails and extend transversely thereof and behold at right angles tothe type lines to print vertical lines. The rule has an upstandingportion 20 and two lateral flanges 21, 21. For strength, the upstandingportion may be made wider than the mark desired to be printed, and theedge portion tapered to a narrow line, as indicated by the bevels 22.The rule is curved concentrically of the segment or drum, so that itseats snugly on the face of the rail. Its side flanges 21 may abut thelines of type, as shown in Figs. 2 and 4, or they may abut suitableclips or plugs held between the rails. Some of such clips are shown at30. As there shown, they consist of channel-shaped spring members havingoutwardly bowed sides which are sprung in between the rails and extendbeneath the overhanging ledge sufliciently to frictionally grasp therails and hold themselves in place. To hold the rule on the railsagainst outward radial movement, the clips may be formed with lips 31overhang ing the side flanges of the rule.

The type, together with the clips of some suitable form, hold the ruleagainst shifting lengthwise of the type lines and against movement awayfrom the rails. To prevent the rule shifting circumferentially about thedrum or segment, I provide lugs projecting in from the ruled strip andadapted to e11- ter the space between adjacentrails. Such lugs are shownin the drawings at Qel. They are made by cutting through the flanges 21and turning downwardly a portion of the flange adjacent to the cut. Thecuts are made in pairs a distance apart substantially equal to thedistance across the head of the rail, so that, when the lugs are turneddown, they may engage opposite edges of the heads of a rail. The space25 between the downturned lugs is left in the original curve of theflanges and rests on the top of the rail, the opposite'edges of whichthe adjacent lugs engage. There may be as many pairs of downturned lugs24: on the rule strip as desired. That is, on a very short strip, onepair of lugs on each side flange engaging the head of a single rail, issufficient. For longer strips, two or more pairs on each side arepreferable. The engagement of occasional rails I have found amplysufficient to hold the rule.

It will be seen that my column rule may be very cheaply constructed andmay be easily put in place on a drum or segment, either before or afterthe type has been installed therein. lVhen in place the rule may beheld, either in conjunction with type or independently of the type. Bymounting rules alone on the drum (holding them by the clips) I may printvertically ruled blanks, or I may print a ruled form with type betweenthe lines. If desired, horizontal ruling may be accomplished at the sametime by dash type, or line slugs occupying the type channels, as is wellunderstood.

I do not desire to limit myself to the precise details of constructionand arrangement above described, as it is obvious that differentmodifications may be made therein with out departing from the essentialfeatures thereof, as defined in the appended claims.

Having thus described my invention, what I claim is:

1. The combination, with grooved type and a holder therefor havingoverhanging rails, of a column rule adapted to be mounted on the face ofsuch holder between type in lines, and tongues no wider than thedistance between the rails and extending from the supporting edge of thestrip and spaced to enter channels which the type lines occupy.

2. In a duplicating machine, the combination, with a rotary printingdrum having a plurality of undercut channels in its periphery, of typehaving flanges fitted in said channels, and a rule strip having aprinting surface curved in concentric relation with said drum heldbetween said flanged type and having lugs extending into theintermediate portions of the channels but not into the undercutportions.

3. The combination of a drum-like typeholder having a plurality ofparallel undercut channels in its periphery, type having flanges adaptedto fit in said channels, and a rule strip having a printing surfacecurved in concentric relation with said drum and having inwardlyprojecting tongues which are no wider than the throat of the channels,whereby the rule may be inserted between typematter preexisting on thedrum.

4. In a duplicating machine, the combination with a rotary printing drumhaving a plurality of undercut channels in its periphery, of type havingflanges fitted in said n channels and a rule strip having a printingsurface curved 1n concentric relation with said drum and having a radialdimension tongues which are no wider than the throat of the channels,whereby the rule may be inserted between type matter preexisting on thedrum.

6. The combination of a drum-like type holder having a plurality ofundercut channels in its periphery, grooved type adapted to fit in saidchannels and project beyond the surface of the drum, and a column rulingdevice adapted to be mounted on the face of the type holder between typethereon, said device consisting of a single integral piece formed with acentral arcual portion rising from the drum to the same height as thetype, flanges on the two sides of the arcual portion, and downwardlyprojecting lugs no wider than the throat between the drum channels,whereby the rule may be inserted between type matter preexisting on thedrum.

7. A column rule comprising a printing strip having a lateral supportingflange and a lug formed of a downwardly turned cutout portion of saidflange.

8. A column rule consisting of an arcual strip having lateral supportingflanges and lugs consisting of downturned cut-out portions of theflanges.

9. A column rule consisting of an arcual strip having laterallyprojecting side flanges, and integral lugs projecting downwardly fromthe side flanges.

10. A column rule consisting of a curved strip having an upstandingcentral portion, laterally projecting side flanges, and integral 7 lugsprojecting downwardlyfrom the side flanges.

11. A column rule made of a single integral piece comprising a centralstrip, lateral flanges 011 opposite sides thereof, and lugs consistingof down-turned cut-out portions of said lateral flanges.

12. A combination, with a rotary printing member, of a concentricallycurved col umn rule having a printing strip and lateral supportingflanges, and lugs comprising out out portions of the flanges turneddownwardly.

13. The combination, with a rotary printing member having rails parallelwith the axis, of grooved type held between said rails, and a columnrule curved concentrically of the printing member and extendingtransversely of the type and having laterally projecting flanges restingon the face of the rails, said flanges being provided with lugs turneddownwardly into spaces between adjacent rails, the lugs being arrangedin pairs spaced apart a distance corresponding to the thickness of therail head.

14. A column rule comprising a printing strip and laterally projectingflanges, and lugs formed by turning down cut-out portions of the flangeson opposite sides of the strip, said lugs being grouped in pairs on eachflange.

15. A column rule comprising a printing strip and laterally projectingflanges, and lugs formed by turning down cut out portions of the flangeson opposite sides of the strip, said lugs being grouped in pairs on eachflange, the lugs of each pair extending diagonally downward toward eachother and having their ends a suflicient distance apart to engage thehead of the typeholding rail.

In testimony whereof, I hereunto my signature in the presence of twowitnesses.
